The birth control pill. This little pill has had such an influence on human development and can also be seen as aiding in the advancement of many countries today. But do many millennials and Generation Z'ers understand just how big of a deal this is?

Those of us in this generation have known nothing else other than this pill being a part of our lives. But what about our parents and grandparents. Do we really understand just how different the world was for them?

When you really think about it, this pill allowed women to have so much more freedom and opportunities that previous generations never had. But like anything else, when you grow up not knowing how different things were, you probably don't have the same level of appreciation for it.
